BAKERY QUALITIES OF GRAIN — CAMBRIDGE, GREAT BRITAIN

In Cambridge in August 2012 Plot Feeds Ltd company on the basis of national agricultural centre Niab-Tag, Great Britain, conducted a number of experiments on CAD separators. In particular, researches concerned the impact of calibration of wheat with the CAD separator on the change of the Hagbert number (falling number).

Hagbert number – indicator of flour quality, the optimal value of which is – 250. Hagbert number in flour that is less than 200 leads to the fact that dough becomes sticky, bread-crumbs rough, dark with a sticky texture, and noodles or paste from such flour is fragile and soft.

The research was carried out on three varieties of wheat: Hereward, Solstice and Cardiale.

In first experiment substandard material with the low Hagbert number after the first calibration on CAD machine was improved in 2,3 times, and when re-calibtaed in 2,9 times (see table 1).

Table 1
Variety Initial hlw weight Initial hagberg % grain taken hlw after cleaning hagberg after cleaning
Hereward 70,3 98 64% 77,8 222
Hereward 74,7 104 80% 80,1 227
Hereward повт. Тест 74,7 104 50% 81,2 342
Solstice 68 211 50% 78,3 382
Solstice 69,3 216 72% 76,8 342

In second experiment the task was: as much as possible increase the Hagbert number with the help of grain separation on CAD machine. Results showed that in 2,6 times after first separation and 3,5 times during second (see table 2).

Table 2
Variety Initial hlw weight Initial hagberg % grain taken hlw after cleaning hagberg after cleaning
Hereward 74,9 116 72% 80,6 296
Hereward повт. Тест 74,9 116 30% 82 401
Hereward 75,8 154 72% 80,7 359
Cardiale 75,9 260 64% 79,8 387
Solstice 70,8 193 76% 76,9 368
Solstice 78 280 86% 80,3 348
Cordiale 76,3 233 70% 79,9 350
Solstice 64,4 204 68% 77,9 304

In third experiment the task was to obtain the optimal Hagberg number – 250. After the re-separation of it was achieved (see table 3).

Table 3
Variety Initial hlw weight Initial hagberg % grain taken hlw after cleaning hagberg after cleaning
Solstice 74,8 243 80% 78,4 319
Solstice повт. Тест 74,8 243 92% 76,8 250

Conclusions: Separation on CAD machine – is simple and highly-effective means of improving the baking qualities of grain!

Recommendations: CAD separators are recommended to be used in technological lines of the flour production, especially with low quality of initial grain.

We remind, leaders of the flour-grinding industry of Ukraine, such as: Myronivsky Hliboproduct, Luganskmlyn, Khmelnitsky Mlyn, Milam and others are our business partners and use in their work CAD separators.

We invite enterprises of the flour-grinding industry to cooperation!
